A Review of Current Techniques for Sampling Freshwater Crayfi sh
Pages 16

Simply stepping into a waterway can reveal a surprising amount about crayfi sh populations. In a stream in Missouri, USA, several species may dart away from your footsteps within the same riffl e or pool habitat, while a world away in the North Island of New Zealand, the resident single species of crayfi sh would be so well hidden during the day that you could walk for hours without knowing they were there. The most revealing thing about stepping into a crayfi sh’s habitat is fi nding that the best method to sample effectively depends on species-specifi c behaviour and the type of waterway you are standing in.
